Using a second processor and operating system to power the Instant Media Mode (IMM), Lenovo claims to have increased the battery life by up to ten hours compared to the previous model.

The Qualcomm dual core processor offers up to 16GB of memory and uses a custom Linux-based operating system.

IMM allows operators to watch videos, view photos, listen to music and browse the web while keeping the rest of the unused operating functions switched off, preserving battery life in the process. Once the battery is drained, Rapid Charge can restore 80 per cent of the charge within just 30 minutes.

Lenovo has unveiled its ThinkPad X1 Hybrid laptop, which it claims is a significant enhancement of the popular X1.

Using IMM is said to make the interface more like operating a smartphone, but users can switch from Instant Media Mode to windows with just one click.

Also new from Lenovo is the company's first ultrabook for business use. The firm claims that the ThinkPad T4300u provides the same thin and light designs found in consumer ultrabooks without sacrificing business-class performance.

Buyers will get their choice of the latest Intel Core processors and either Intel or Nvidia graphics cards, along with a selection of solid-state drive options. Alternatively, customers can select up to 1TB of HD storage.

"The ThinkPad X1 Hybrid and T430u ultrabook represent the next generation in thin and light computing," said Dilip Bhatia, vice-president of the ThinkPad Business Unit at Lenovo.

"From small businesses that literally live their business on the road to corporate professionals working in a managed environment, these new crossover laptops fundamentally change the way people think about mobile computing technology."

The ThinkPad X1 Hybrid laptop will be available from the second quarter of 2012, priced at around $1,599 (£1,036), followed by the $849 (£550) ThinkPad T430u ultrabook in quarter three.
